Patented Aug. 27, 1918:

2) SHEETS-'SHEET h w K W .w w f w w of a tube throu h whi'eh air under pressure may be received from a siiitahle source of supply. The oil inlet 17 is also threaded for connection with a supply tube and said inlet is provided with a .transversely dis'posed serew valve 1'8 the stem ot' which is surrounded by a packing glaud 19, said steni being also provided with a handle 20 whereby it may be eonvenienlly rotated.

The barrel 15 is provided intermediate the air inlet 16 and the oil inlet 17 with a wall or diaphragm 21, a second partitiou wall 22 being formed intermediate the oil inlet and tail end of the barrel or easing. 'The oil ehamber O' which is located between said partition walls has a downwardly extending pet eock 23 Whereby the oil ehamhe'r may be cleaned and drained. The partition walls 21 and 22 have'oentrally disposetl th'ieaded openings. eated in the opening wn the wall 21 is a bushing 24 having a nip,ple 25. The longitudinal bore 26 of the bushing; and nipple is eountersunk at its front end to provide a seat 27 for a screw valve 28 whi'h is in threaded engazement with a (',ap 29 whieh forn'is a closure for the front elid of the easing, said valve stem being surroundecl.. by a paekinp; gland 30 and provided with means, not shown, whereby it may be readily rotated to move said valve in and out of engage- 'ment with its seat for controlling the passa e of .air from the source of sup ly to the oichamber. The rear end of the lbore 26 is preferably enlarged or countersunk as seen at 31 in Figs. 3 and 4. "The bushing .24 is provided with a head 24' of hexagonal or other non-cireular Shape to enable said bushing to be eonveniently reaehed and removed by means of a suitable wrench which may be eonveniently applied when the eap 29 is removed. This Will enable a bushing having a. bore of a different diameter than that shown in Figs. 3 and 4 to be substituted when desired, a specimen of such bushing having been shown in Fi 6 in which the bore, here desi ated by`26', is of larger diam'eter than t at shown in vFigs. 3 and 4, thereby obviouiy aflording a larger passage for the more generous 'supply o airl to the burner' nozzle which, as wlllV be hereinafter deseribed, receives' the discharge from the bushing. f

The' top of the easing o'r barrel 15 has an obliquely disposed.. swelled portion or enlargement/ having a longitudinal inclined bore 33 the forward end of which communicates with the interior ,df the easing 15 to the rearward of the partitioniwall 22. A passage 34 connect sthe boi-e 33 with the oil ehamher or spacel) :there being a defleetorv :35 within the boi-e bp'awhieh overhangsthe port or passage 34. 4^.;3.';-passa e 36 eonn'ects the h'ore'33 with the 'a' "*tcham .er or space A within the casing IF) "'aid ai'r Chamber bein the space forward o the partition 21 whic Lew/,820

eon'imimieates with the air inlet lti. The liore 33 is enlarged adjaeent' to thel pass-:age 3-56 to form a seat 37 for a sereu' valve 38 theI stem of which is surrounded by a paeking glaud 39 and provided with a hand wheel 40 for conveniently manipulating the same.

Threaded into the opening in the 'partitiou wall 22 is a nozzle +1 which projeets through the tnil i'nd of tlu` t'asing. said nozzle being also provided with a foru'ardly extendingr.f'laringr or t'unni'l shaped intako 42 that exteuds within the oil 'hn|nh'r t) and within u'hirh t'ht` nipph' 25 ot' tluI plug 24 ['xtends. Tlu` intake i'unnel is provided u'ith a cirrumferrntial series of apertures 415 \\'hi.'h are pret't'rabl)y inrlinud in an inu'ard and rearu'ard direotion as host seen in Fig; 3 .\n auxiliary nozzh'. lt which surrounds the now/.le ll is thri'adrd into the tail end of the rusing. The nozzh' l-l is provided with a seat 43 i'or the taprri'd end -H'i of the nozzh' ll and it l'ollou's that adjustment of the nozzlo H lhil area of tho annular disehargo opening Iii'tu'ei'n tlu` seat, 45 and the tapoi'ed end of tlu` nozxh' lt; may he varied.

From the forrgointgr dest'ription taken iu t'onnet'tion with the drawinzs hen-to anneXed the operation and advnntagjes of this invention will be readily understood. Air under pressure may lie admitted through the inlet 16. Assumingz the valvel 28 to bo open and the valve 38 to he seated`I the air will pass through the bore ofthe plug 24 and nipple 25 to the nozzle 41 produei'ng a partial vaeutnn in the. oil Chamber and inducing oil to pass from the source of supply to the inlet 17, the quantity of oil being regulated by the valve 18. The oil thus,` entering` will he atoi'nizod and the fuel mixture will be ejeetod through the main nozzle and the lnouth of the auxiliary nozzle 44 issuing from whieh it. may bo ignited. If now the valve 38 bo unseated, a portion of the air under pressure will pass through the passage 36 and liore 33 to 'the tail end of the easin siphoning a pol'tion of the oil from the e iamher O through the port or passage 34, atomizing the same and ejeeting'ti fuel mixture through the annular space between the main and au'xiliary nozzles, the mixture thus-ejected being eommingled with the .mixture issuin through the main nozzle 4.1 and ignit-ed as 1t is sprayed into the furnace. .If the valve 28 be seated,t,he fucil m'ixture will issue through the spaceA between the 'main and auxiliury nozzles only. iIn all cases the passg'e of mr as well as of oil may beicompletely and accurately regulated 'by the valves provided for the Purpose, thus enabling'a" rieh-mixture to be projeeted through the main' nozle 'and a lean mixture to -be pro- Jeeted through the space intermediate the main' and'auxiliary nozzles, or-vioe versa as. may be lrequired m order to produce the most iso desiralle und henelicinl result. Ordiinirily when the hnr'ner is iii operation hoth vnlves 28 and 38 will he unseuted so thul fuel mixtnre 'will he ejeeled through the nmin nozzle and also through the space intermediate the nnlin und anxiliury nozzles. ['f now, t'oi' any reason, either .nozzle should he. ohstrueted, the other' nozzle will still eontinue to funetion without interruplion, therehy prereniing any Sudden end detriniental lo'wei'ine' of temperature within the l'urnuee. to whiifi the hurner is applied. proveii hurner is extremely simple in its conh'truetim] und arrnngeuu'nt ot' paris and ofisueh :i nature ns to render ull the parts thez'eo'f eusily iiceessihle for Hneh ndjustniente| und. repairs :w inny he found neces- .Lsary` Hnv'ing deserihed the iinfenlion n'hut we rhiiui :is new is:
